Idk what to do

So, I'm 38 weeks today, but for three days my stomach been feeling a little tight and last for 3-5 mins and then goes away. Sometimes I can't even walk , I feel like my bladder is coming out. I know it's weird. But that's how I'm feeling. I have not gotten any sleep last night because it was happening to me all night. My water didn't break nor lost my mucus plus.idk of its the baby stretching because she's running out of room ..ugh So I want to know what to do. Should I go to the hospital? Or it's normal?
